Warning signs your immune system needs help
The problem

Immune ageing begins as early as 40

As you age, T-cell production and function decline while chronic inflammation quietly rises. This imbalance is linked to more infections and age-related conditions, and it starts decades before you feel it.

  • 01
    T-cells decline. Your body's elite defence team gets smaller and slower.
  • 02
    Inflammation rises. Low-grade chronic inflammation creeps up, a key driver of decline.
  • 03
    You feel it as fatigue. Tiredness, slow recovery and getting sick more often.
Meet T-cells, the missing link

Not your average immune booster

Formulated with GPComplex®, a patented bioactive polysaccharide clinically proven to enhance T-cell proliferation and modulate immune response.

It doesn't just boost. It helps build a balanced, resilient immune system, the foundation of healthy ageing.

How GPComplex® works

A patented extract, two powerful pathways

About 70% of immune cells live in the gut (GALT). GPComplex® is a patented extract from Chinese licorice root that works in two ways:

  • →
    Directly. Activates receptors on immune cells in GALT, triggering T-cell activation.
  • →
    Indirectly. Acts like a prebiotic, feeding good gut microbes to strengthen the gut barrier.
Clinically proven

Proven in a Phase II clinical trial

Randomised, double-blind, placebo-controlled, multi-centre trial, 240 subjects.

FAQ

Got questions? We have answers.

It contains GPComplex®, a patented bioactive polysaccharide from Chinese licorice root. Clinical studies show it supports the body's natural immune regulation and enhances T-cell function. After 40, the immune system weakens and chronic inflammation rises, and a balanced, resilient immune system helps you age well.

Felt benefits like easier digestion and more energy are often the most obvious. Longer-term immune benefits usually take around 2 to 3 months. It's also normal not to feel anything immediately, your immune cells and gut microbes are at work inside.

It's made from a 100% natural plant extract with no reported side effects, no synthetic chemicals, additives or fillers. If you have a known allergy to licorice or polysaccharides, consult your physician first.

Yes. It can be taken consistently on a long-term basis. Clinical research and its long history of use suggest a good safety profile.

There are no known interactions with over-the-counter or prescription medications. If you have any concerns or existing chronic conditions, we recommend consulting your physician before use.
